Specification of Application med Marche,

T all whom t may concern Be it known that I; MAURICE- LnvIsoN, a citizenof the United States, residing at Chicago, in 'the cbunty of Cook andState' of "I'lli'nois, have invented certain new andl use- ":t'ulImprovements in Annunciator-Cabinets,

of which the 'following is a specification.

My invention relates to' improvements in annunciator cabinets, andparticularly in some of its features t'o annunciator cabinets vvhereiii'electric lamps are used 'for effecting "'the signal display. V

One o the objects of my invention is' t 'provide ailnshvtype, all-metalcabinet constructlom 'which is simple, easily manufac "tured, fabricatedlargely of a plurality of similar partst'and susceptible of embodimentlin neat. and 'attractive form.

A further object' of my inventionv is td 'provide a construction otthe'cha'r'acter described, vtherein all of the lamps, and theirassociated parts, are mounted on a unit lamp-base structure adapted,when in use, to be fixedly secured Within the casing, but adapted, also,to be moved with respect to the casino to a position giving ready accessto the wiring terminals at the back of the lampbas structure. Anotherobject of my invention is to p'ro-, vide improved means for mounting thelamps and for :conining'the illuminating efl'ect of each lamp to itsappropriate lens, so that false illumination of' any annunciator targetsother than that directly associated with the energized lamp may notoccur.

Still another object of my invention is to provide an improvedconstruction, arrangement, and'mounting of the lenses associated withthe lamps, and of the designating char- 40 acters or indicia `Which areassociated With lenses. A particular 'object of my invention 'in thisregard is to provide such construc-` tion that the designating indiciaof the sev-,y eral lenses maylnot be visible except when' illuminatedfrom the rear, as upon the glowing of the respective lamps associatedthere 'ivithl l Other and further objects of my invention will becomeapparent to those skilled in the art from the following descriptiontaken in 'conjunction with the4 accompanying'draW-- 'ing in which I haveillustrated, for purpose' Letters'latent.

rinvention 'that is 'parti'cul'arl'yl adapted "for li'ospitals'ignalingservice, and that I have i'ound 1n practice to be satisfactory andellicient.

Fig. '5vis'a'n enlarged rear elevation on line 5 5" of Fig. 8.' Fig. 6 is anenlarged perspective view of an index unit. Fig 7 is an enlargedperspective detail illus- 'ratin'g theihounting of the lamp carryingase.

' In' thel particular' construction shown in the draiving's 10 indicatesa'ivall plate or border frame having an opening 11 closable by a door12, 'hinged at onefside, as at 18, and prbvided with any suitable lockor latch 14. Associated With the border frame 10 is a' box member 15,preferably of a single `piece drawn metal constructiom provided atsuitable 4points with knock outs 15 to admit the requisite Wiring ofsaid box having its'face opening fitted' Hush against the 'rear face ofthe 'latelO and having at its corners lugs 16 bo ted' asat 17 to saidplate. In 'hospital installations and the like the entire "e'i'teriorsurface of the wall' plate' and door taking through said parts areconcealed. The' d'oor or 'closure 12' has cut therein, in

'in vertically alining tiers, 'apertureslS in which are mounted the lensstructures, each of which is generally indicated at 20.' Each lensstruc-turepreferably comprises 'the plano-conveniens 21, having itsplanar surface ground and its 'curved surface clear.

This lens is" mounted in a holder 21 comprising a rirn' 2Q and 'atubular body 23, said rim underlying a border portion of the pla- I'narsurface'of'the" lens and spun'over its "c'nveir border, andy saidtubular body in'terof full disclosure, an embodiment of my fitting Withthe aperture 18 and extending are enameled so that all the screws andbolts I any suitable relative arrangement, generally through and beyondthe door pleite 12. In the tubular portion 23 are formed retainingspring fingers 24, which, when the holder is in place, act. against therear face of plate 10 to retain the holder in position.

I prefer that the distinguishing indicia associated with the respectivelenseswhether numerals, letters or the likebe mounted in border framesdetachably connected with the lens holders-so that the respectiveindicia of the diierent lenses may be changed or transposed as desired.In the particular construction shown (Figs. 5 and 6) 25 represents ingeneral the indicating unit consisting preferably of a translucent disk26, of mica or other suitable material, bearing an opaque index mark 27,which may be a black paper numeral pasted on thedisk, said disk mountedin a rim frame 2S adapted for insertion and selt retention in thetubular portion of the lens holder. Specifically 29 and 30 indicateopposing rim rings, ring 29 having projecting rearwardly therefrom a setof retaining spring fingers 31, adapted to make Jfrictional engagementwith the interior surface ot the tubular member 23 of the lens holder,and also havinga series of clamp lingers 32, which are inturned over theedge of a complemental border ring 30, so that the two rings 29 and SO,united by the fingers position and reinforce the translucent disk.Manifestly the index unit 25 may be inserted in any lens holder so thatthe mica disk is brought close to the ground planar face of the lens andthe indication 27 is thereby properly positioned. When light falls on alens only from the front; as when there is no illumination within thecasing, the numerals 27 are substantially invisible; the ground planarfaces of the lenses making them appear frosted when viewed from infront. But when illuminated from the rear the numerals stand o`utboldly, as does the numeral 3;, in Fig. 1.

A lamp is provided Afor association with each lens, and these lamps andtheir appurtenant parts are mounted on a vsupporting trame suitablysecured within the housing. In the specific construction shown I provideupper and lower pairs of clips or angle-brackets, 40, forming verticallyalining couples having their vertical legs riveted or otherwise securedas at 41 to the wall plate 1() adjacent the upper: and lower edges otthe opening 11. llachjsaid clip extends past the edge of the dooropening to form a stop for the door and jis rearwardly bent to provide ahorizontal :supporting surface. WYhile I preferably provide four ofthese supporting clips 40 for a cabinet structure of any ordinary size,more may be vided` 1t required, in extreme cases.

pro- The lam -carr Ying base or carrier 42 is a metal l ertures platehaving its upper and lower edges for.- wardly bent to form flanges 43intertting neatly between the supporting flanges oi the brackets 40, andypreferably having its vertical edges rearwardly bent into flanges 4.4,for strength and to prevent buckling. Plate 42 is preferably mounted onthe clips by detachable fastenings such as vertical bolts 46, so that byremoving the bolts from the upper and lower clips forming the couple oneither side of the median vertical line of the structure, the lamp plate42 with all of its pertinent parts may be swung pivotally upon bolts, asbest illustrated in Fig. 4. Specifically each liange 43 is slotted as at45 at right angles to its forward edge, and the bolts 46 taking .throughbrackets 40 and the slots 45 s'ecure the plate structure in place.Manifestly such connection gives the plates a susceptibility toadjustment toward and from the Jfront 'of the casing, and as shown inFig. 4 the removal of one couple vof the bolt connection 46 enables theplate structure to be swung on the remainving couple of bolt connectionsas a pivotal axis` so that the plate structure may be swung out throughthe open doorway to reversed position exposing the rear side of theplate outside of the casing to facilitate the placing of the electricwiring. To this end Iso proportion the plate and the parts connectedtherewith that they may be swung through the open doorway 11 withouthindrance.

Each lamp 50 carried by the plate 42, of course alines axially withitscorresponding lens 21, and each is inelc'sed within a shiel'd 51, toprevent diffusion of the light, each such shield preferably extendingclose yto the door 12 and preferably overlapping, in a fore and aftdirection, the inner end o the tubular portion 23 of the lens holder. Inthe speciic construction shown the shields 51 are drawn metal cups, thebase of' the cup and the plate 42 being suitably apertured to receivethe insulated body of a lamp socket or receptacle 53, which extendssuitably in rear of the plate 42 to expose its wiring terminals 54 atthe rear ot' said plate. As best shown in Fig. 7, each lamp socket bodyand the shield cup appui-tenant thereto may be secured to the base plate.42 jointly by bolts 55. Manifestly the fore and aft adjustment of plate42 permits the front edges of all oi? the shields to be brought as closeas need be to the rear face of the door.
